[SOLVED] unable to send mail to external domains

[gtdaqua]

I have setup ZCS on Ubuntu 7.04 with public IP successfully and am able to receive emails to my @example.com from external domains.

I am getting

Message not sent; one or more addresses were not accepted.
Rejected addresses: <emailaddress@domain.com>

However I am not able to send emails via Web-client to gmail or yahoo mail. I am able to send emails within my domain?

Why wont Zimbra by default send emails to external domains?

Am using OpenDNS on Zimbra Server.

Any help will be much appreciated.

Check the settings described in this article.

postconf mynetworks
mynetworks = 192.168.0.32/27

my local machine is 192.168.0.40

so now i have given

zmprov modifyServer mail.bksec.co.in zimbraMtaMyNetworks '127.0.0.0/8 172.16.1.0/24 192.168.0.32/27'
postfix reload

and am getting:

postconf mynetworks
mynetworks = 127.0.0.0/8 172.16.1.0/24 192.168.0.32/27

172.16.1.0 is the secondary IP (internal) for the Zimbra server.

Yeah it works now. But still have one setting to test. Because its a web client i assume I dont have to give my local network IP.

You probably want to add

192.168.0.0/24

instead of the single IP you've put in there so your LAN users can relay through the server, web mail would be OK but not if the used a fat client like Thunderbird.

Thanks for all the fantastic and super-fast response!

thats not a single IP. Thats a segmented LAN. The range is 192.168.0.33-62.
So I need to add all local networks according to the subnet, right? (not just 192.168.0.0/24 to have all 254 computers?)

thanks.

one simple question.
can i have a 2nd zimbra server just send emails. Basically load should be shared between two mail servers (one to send and one to receive). We have about 350+ users.

Sure it's called a multi-server setup, you could put the LDAP & Mailstore etc on one box & the MTA on another.
You can do all sorts of things - this is way more than you need but it's a good example:

Sorry, I was daydreaming there. Yes, you can have a segmented LAN if you choose or the complete subnet - whatever fits your set-up.

Awesome!

Thanks, Guys! I will keep this as a reference. That architecture looks really cool.
